Yea they're pretty nice & robust enough for outdoor use but I'd buy a couple boxes to be safe. I know my way around castings since that's what I've over the years to help pay for this & other hobbies so have to say I'm impressed after spending a half hour with these.
Nicely detailed, very clean Zamac links without any trace of flash & its hard to notice the injection points since they are one end which will be easy to conceal. Pins are brass, smooth shank with head & fit nicely, a little too smooth for my taste when inserting into the track but given their size I didn't expect IMPACT's knurled pins. You'll certainly want to use CA to retain the pins after assembly.
Overall very happy & already am lobbying for more 1/16 track & sprockets. Would love to see them do some more mainstream subjects so I can ditch some of my MATO tracks for something a bit more upscale.
I'll give them
